To all whom it may concern Be it known that T, ARTHUR HEINEMIANN, a subject of the King of Prussia, residing at 223 North End road, West Kensington, London, W., England, have invented an Tmproved Process for the Synthetic Production of Glycerin, of which the following is a specification. I

The invention relates to an improved process for the synthetic production of glycerin. 7

According to the present invention propylene, which may be obtained by the union of acetylene and methane, or in other ways, is treated with chlorin, as a gas or as a suitable compound so as to produce dichlcrpropane. This chlorination may be done in the presence of actinic rays. The dichlorpropane so produced is converted into allyl chlorid and the latter into trichlorpro-pane. Finally the trichlorpropane is mixed with water, with or without the addition of an alkali compound, and then heated so as'to produce trihydrorrypropane or glycerin.

The improved process may be carried out in the following manner: The propylene is obtained in any suitable Way, but preferably according to the process described in the specification of my application for Letters- Patent of the United States, of even date herewith, Serial No. 770,221. The propylene is converted into dichlorpropane by ad mixture with chlorin gas or by treatment with a suitable chlorin compound. The reaction is represented by the following equation n,ccnon, d or ein,o-oien cn,

+ Cl ill The trichlorpropane is then mixed with Water, wlth or without the addition of alkali compounds such as sodium hydrate, poles-l sium hydrate, sodium carbonate, or calcium hydrate, and heated so as to produce trrhydroxypropane or glycerin.

Having now described my invention what I have invented and desire to secure by Letters Patent in the United States is as follows a In the manufacture of glycerin, the process of converting dichlorpropane intoallyl chlorid which comprises dropping said dichlorp'ropane on a heated alkali.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ARTHUR HEINEMANN.
